    Huh!?  The \(?:..\) is actually both useless and harmful here and should be
    removed (if possible).

It isn't useless, since it prevents confusion of back-references to
explicit groups.

I think the only way to make this feature work really right
is to add a regexp feature that substitutes something else 
for bunches of spaces, but does it only when the spaces
are not inside something else.  It was easy to do, so I did it.
